Choosing a seal material for Texaco Meropa 220, No Lead

The table above rates every common O-ring elastomer for service in Texaco Meropa 220, No Lead on an A–D scale. A is Excellent, B is Good, C is Fair (test before relying on it), and D is Not Recommended. An X indicates insufficient published data.

For Texaco Meropa 220, No Lead, the strongest candidates are Nitrile (Buna-N), Hydrogenated Nitrile, Fluorocarbon (Viton), Perfluoroelastomer, Fluorosilicone, Neoprene (Chloroprene), Polyurethane, Aflas (TFE/P). These ratings are representative at ambient conditions (~20°C). Compatibility shifts with temperature, concentration, pressure and exposure time, so always validate the material against your real operating envelope before committing to a design.
